Expansion is increasing the size of an object due to the change in temperature or increase the length. Expansion took place on three properties of the object that is solid, liquid and gas. All three of these substances is a supporting element in the earth.

The nature of the solid expansion in the elongation will occur, this is called the expansion length (for one dimension). The second is the expansion area (two dimensions), this happens to objects that have a size and a final two-dimensional nature of the expansion is the expansion volume gas substances (for three dimensions).

For other substances, the liquid and gas substances happened only volume expansion alone, especially on gas substances are usually taken the value of the volume expansion coefficient equal to 1 / 273.
